DevOps is a methodology for software development, but in a different way. Thus, he will use communication as a fundamental factor to successfully integrate teams, a new mentality between the operations, infrastructure and development departments, which suggests collaboration. Mutual learning and the exchange of information and ideas will be the main gains for the business.
DevOps is nothing more than the organization of the work processes that will integrate these teams, so that, together, they can follow the technological evolution of the market and discuss whether the business can benefit or not from these innovations: what are the best tools for the company, what are the main needs and where are the biggest gaps, especially among software developers and IT infrastructure professionals.
Companies can release new versions of software and changes to their environments with great frequency. In order to be more agile it is important to insert the applications and the released changes considering the DevOps guidelines.
Muitas delas possuem problemas em fazer a implementação e as alterações dessas versões, já que na maioria das vezes, o processo é feito de forma manual, portanto, a chance de existirem erros é muito maior.
O maior desejo nesses casos é ganhar flexibilidade e rapidez no processo de implementação. E como se ganha essa agilidade e diminuímos a incidência de problemas?
Para conseguir reduzir essa incidência de problemas e conseguir aumentar essa flexibilidade é preciso ter automação.
The first step in implementing DevOps in your company is to list the goals you want to achieve and have the ideal and effective tools to enhance performance.
Some of the tools most used by companies that bet on DevOps are divided into five groups, namely:
Source code repository (Git, CloudForce, TFS, Subversion);
Build Server (SonarQube, Jenkins, Artifactory);
Configuration Management (Puppet, Ansible Salt, Chef);
Test Automation (Selenium, Water) and;
Virtual Infrastructure (Amazon Web Services, Microsoft Azure and VMware vCloud).
There are some points that deserve attention during this process. Ideally, your team should have a direct and simplified view of production, preparation and testing. Each team must be able to autonomously monitor their performance observations.
In fact, performance must be a basic and main requirement of your products. Value it and make your team also notice and understand its importance. It is a feature that must accompany your product from the initial idea to completion and delivery.
There is only one way to guarantee the total performance of your product: always testing it. Create a continuous testing environment, because the sooner you receive feedback, the easier it will be to correct errors and improve the quality of your product.
When we reinforce the idea of fixed and concrete goals, they also need to be shared with your employees. The whole team needs to be aligned and at the same pace of production, so that together they achieve the expected result.
Focus and always aim to provide the best experience for your user and customer. It is necessary that after the implementation of DevOps they notice an improvement in the quality of your product or service.
The entire production process of your product must be monitored, especially when it comes to performance. In a completely automated environment there are five categories that deserve more attention and observation. Are they:
Development cycles: in this step, more technical details are verified, such as, how many resources are being incorporated, how many errors have been identified and how many have been corrected;
Implementations: when your product fails you need to know what was responsible, so monitoring the entire route is essential;
Vulnerability: knowing the vulnerabilities of your product allows you to think and define actions to solve them and deliver the best final product to the customer;
Server health: There are several ways to carry out this monitoring and it will ensure that the infrastructure to receive your product is fully functioning and available;
Application performance: again, product performance is high. It is necessary to ensure that your production works as expected by you and especially by the customer.
These are points that need to be addressed and mitigated each day.
Microservices through solutions in containers have come to solve problems in monolithic architectures, in which a single system is in charge of managing the database, back-end, front-end, when it is necessary to maintain a system function. the entire application is unavailable impacting the company’s business.
Through microservices, the container will package only what is needed in your application, leaving the developer free from concerns such as computational resources, libraries, binaries of other functions that will not be affected.
Continuous integration and continuous delivery today are the reality in environments where there is a need to increase the speed of deployment, process automation and monitoring, in order to ensure that your QA, Approval and Production environment are level.
There can be several types of methodologies within a given project, so nothing will ever be static. The team is made up of people and not robots, it is necessary to adapt situations so that people understand the process.
Differences from project to project will always allow fields for some modifications that will be necessary. Using multiple methodologies is one way to implement DevOps, because it understands the whole context.
What usually disturbs the development team is the famous “cake recipe” tactic, that is, having only one way of working. Those who are attentive to different forms will be able to adapt better to different situations.
Once again, it is of great value that the teams of developers and infrastructure are integrated. Working together is essential to achieve the desired results.
DevOps is nothing more than the organization of work processes in an automated way, which will integrate these teams in order to carry out implementations and automations that make sense and make the business benefit from technology.
